Dario Antonelli,Sergey Astanin,Giulia Brunocyclopentylidene)chromium complexes (3a-f) through the ring opening of oxiranes by the conjugate base of the pentacarbonyl(methoxymethylcarbene)chromium complex (1); oxidation of (3a-f) with Ce. leads to the corresponding γ-lactones. The extension of the above reactions to oxetane allowed the synthe
